00:20 <horizontally> is there anything smaller than an electron that we can control?

00:20 <horizontally> neutrinos?

00:20 <berndj> how big is an electron anyway

00:22 <horizontally> you can determine its mass if you have an electromagnet and a power supply... and a vacuum pump and an inert gas

00:22 <horizontally> then the electron beam can be visualized however you want with the appropriate applied magnetic field

00:22 <berndj> if you're looking for something with which to expose resist material and electrons *aren't* giving you the resolution you need, maybe you need ions then

00:23 <berndj> more mass == shorter de broglie wavelength at a given energy == better res

00:29 <horizontally> oh right lambda = h/p

00:38 <berndj> so maybe you want a lead ion beam exposure system :)

00:40 <berndj> but even 40eV gives you lambda = 2 angstrom, so unless you want to etch quarks, i think electrons are just fine!
